什么？还没有搭建k8s，那赶紧看看 [K8S] 认证集群搭建吧

容器这么火，我也玩玩，搭个zabbix测试下

1、首先上传 zabbix 相关镜像至 harbor

# docker login 192.168.1.206 #登录仓库

Username (admin):

Password:

#docker search zabbix #搜索下载镜像

# docker pull zabbix/zabbix-web-nginx-mysql

# docker pull zabbix/zabbix-server-mysql

# docker pull zabbix/zabbix-proxy-mysql

# docker pull zabbix/zabbix-snmptraps

# docker pull mariadb

重复以下步骤打tag并上传

# docker tagzabbix-web-nginx-mysql192.168.1.206/mzh/zabbix-web-nginx-mysql

# docker push 192.168.1.206/mzh/zabbix-web-nginx-mysql

2、编辑yaml文件

selector:

app: mariadb-proxy

ports:

port: 3306

protocol: TCP

#kubectl create -f mariadb-proxy.yaml -f mariadb-proxy-svc.yaml #创建proxy数据库

#这里我本来是用 zabbix-proxy-mysql镜像来搭建proxy代理容器的，但是发现全部搭建完后，无法用来监控agent和获取数据，proxy容器内部无法访问外部？。

所以，如果你有足够的耐心看到这里，就会发现，我之前的yaml文件中有zabbixserver和mariadbproxy是给的固定CLUSTER-IP，分别为10.254.0.3 和10.254.0.4。

所以我决定将 proxy安装在 k8s集群任意物理节点上，在zabbix-proxy配置文件中用刚才的两个ip配置就OK了。

过程略，关于zabbix配置什么的参考【Zabbix】项相关文档吧。
